ABSTRACT The family Myrtaceae (Myrtle family) comprises approximately 150 genera and 6019 recognized species. This comprehensive review synthesizes data from 345 studies published between 1956 and 2026 to evaluate the reproductive biology, phenology, floral biology, palynology, and stigma dynamics across the family. The findings highlight substantial interspecific variation in floral morphology, phenological traits, and anthesis behavior, demonstrating that reproductive strategies within Myrtaceae are far from uniform. Palynological assessments reveal diverse aperture configurations, though triangular, tricolporate pollen grains predominate; additionally, pollen viability and stigmatic receptivity vary significantly among taxa. Existing literature remains disproportionately focused on commercially significant genera such as Eucalyptus , Syzygium , Eugenia , Melaleuca , Callistemon , and Myrcia , leaving critical knowledge gaps regarding wild, non‐commercial species that require targeted empirical investigation.
ABSTRACT Amaranthus emarginatus Salzm. ex Uline & W.L. Bray is reported as a new distributional record for India from the Kashmir Himalaya. This record represents a significant range extension of the species into the Indian Himalaya and expands the documented diversity of the Amaranthus blitum aggregate in India. Both recognized subspecies, A. emarginatus subsp. emarginatus and A. emarginatus subsp. pseudogracilis , are documented. A detailed taxonomic treatment, including descriptions, diagnostic characters, a taxonomic note, and photographic illustrations, is provided to facilitate accurate identification. The findings of this study highlight the importance of continued botanical exploration for documenting plant diversity and refining species distributions in the Himalayan region.
ABSTRACT Three species of Physciaceae lichens: Heterodermia koyanoides Elix, Leucodermia circinalis (Zahlbr.) Kalb, and Polyblastidium appendiculatum (Kurok.) Kalb are reported as new records for India from the Agasthyamalai Biosphere Reserve, Southern Western Ghats. Polyblastidium propaguliferum (Vain.) Kalb is a new record for Southern India. Heterodermia antillarum (Vain.) Swinscow & Krog and Physcia undulata Moberg are reported for the first time from the state of Tamil Nadu. A total of 27 species of the family are recorded from the Biosphere Reserve.
